Description of key information
Reaction Product of Bisphenol A diglycidylether (BADGE) with a mixture of IPDA and MXDA was not tested for environmental fate properties instead read-across approach was applied. Reaction products of IPDA with bisphenol A diglycidylether (BADGE) and Reaction products of MXDA with bisphenol A diglycidylether (BADGE) show similar abiotic and biotic degradation properties, therefore, the degradation properties of the asymmetric epoxy-amine adduct were considered comparable.
Additional information
Hydrolysis
Based on the results obtained in the preliminary test according to EU method C.7 and OECD guideline no. 111, Reaction Product of Bisphenol A diglycidylether (BADGE) with IPDA and MXDA was hydrolytically stable at pH 7 and 12 °C (half-life >1030 days at 12 °C). Hydrolysis at pH 4 and pH 9 was assessed using a read-across approach to the symmetrical epoxy amine adducts. Based on the results obtained hydrolysis at 50 °C was 19 days for pH 4 and pH 9.
Biodegradation in water
The asymmetrical epoxy amine adduct Reaction Product of Bisphenol A diglycidylether (BADGE) with IPDA and MXDA was not tested for biodegradation. Instead, a read-across approach was applied using data from the symmetrical epoxy amine adducts Reaction products of IPDA with bisphenol A diglycidylether (BADGE) and Reaction products of MXDA with bisphenol A diglycidylether (BADGE), as these substances were considered to show similar environmental fate properties. Based on the obtained results, Reaction Product of Bisphenol A diglycidylether (BADGE) with IPDA and MXDA was considered not readily biodegradable.
Adsorption/desorption
Based on a read-across approach using data obtained for Reaction products of IPDA with bisphenol A diglycidylether (BADGE) and Reaction products of MXDA with bisphenol A diglycidylether (BADGE) the log Koc for the asymmetrical adduct Reaction product of Bisphenol A diglycidylether (BADGE) with IPDA and MXDA was estimated at 4.82 (worst-case scenario).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
